ELECTROCHEMICAL METHOD AND DEVICE FOR THE DETERMINING THE CONTENT OF DOC AND/OR TOC AND/OR IC IN AN AQUEOUS SAMPLE

摘要

The invention relates to an electrochemical method and to a device for determining the content of DOC and/or TOC and/or IC in an aqueous sample by means of anodic oxidation of electrodes in a closed electrolytic cell, wherein the carbon is at least partially oxidized into carbon dioxide (CO2). The formed carbon dioxide is collected in a closed gas chamber, wherein in the range of the substantially linear rise of the CO2 content in the gas chamber, the speed at which said rise occurs is determined, and said speed is used in an evaluating unit to determine the content of DOC and/or TOC and/or IC.
